Nine

ナイン

Nine is a villain and the main antagonist of My Hero Academia: Heroes Rising.
Nine's original Quirk enabled him to control the weather, letting him instantly summon destructive thunderstorms and even generate a powerful tornado with himself at the center. However, Nine stated that his Quirk was too potent for him to handle, which caused the destruction of his body's cellular tissue.
After being genetically modified with All For One's gene, Nine acquired a weaker version of All For One, which allowed him to steal other people's Quirks and use them as his own. He could steal up to eight Quirks. It is unknown whether he could transfer any of these Quirks to another person. Nevertheless, receiving this Quirk seemed to exacerbate the side effects of his original Quirk and drained his energy much faster.
